I came across this post at Mobhappy by Carlo Longino which highlights two new Nokia phones (1200 and 1208), which have probably generated little interest amongst developers in the West as they are entry level phone, but are particularly interesting (at least to me ) from a socio-techinal standpoint in that Nokia has introduced a couple of features which are aimed for users in the emergent markets. In particular as Carlo notes:

“they support multiple phonebooks — a nod to the fact that in many developing nations, a single handset is shared among several family members or friends”

“they have a call-tracking feature, which lets users set the maximum cost of a call before dialing. This lets users control their spending, but it also helps empower the entrepreneurs in these markets that buy a phone and airtime credit, then resell calls.”

This is great users centric design from Nokia.

BTW if you are interested in the practices highlighted above I recommend this great paper by Jan Chipchase of Nokia.
